The most common early use of Cesium was to evacuate oxygen from vacuum tubes.
It is currently used for many things, including subjects from density measurements to cancer treatments.
The pronuciation is cal-ci-um. For "cal" you can use somebody shouting to another person. For "ci" you can use sea. For "um" you can use a person with a thinking puzzle.
The most alkali element is cesium (Cs), which is located in Group 1 of the periodic table. It has the lowest ionization energy among the alkali metals, making it highly reactive. Cesium is known for its use in atomic clocks, where its precise frequency helps keep accurate time.
Reactivity increase down the group.Ceasium is the most reactive.
There are twelve from the periodic table of elements: Californium Cesium Curium Carbon Calcium Chlorine Chromium Cobalt Copper Copernicium Cadmium Cerium
values and uses of precis
Caesium. Cesium is the American way of spelling it. Caesium is what everyone else uses.
The compound formed between sulfur and cesium is called cesium sulfide.
cesium phosphide
Cesium Nitride
The cesium ion is called cesium ion or Cs+.
The correct name for the cesium ion is "cesium ion" or "Cs+ ion".
Cesium Chromate = Cs2CrO4
The formula for Cesium Peroxide is: Cs2O2
cesium will sink
When cesium and fluorine react, they form the ionic compound cesium fluoride (CsF).
The high reactivity of cesium comes from its tendency to give up the one electron in its outermost shell and become a cesium 1+ ion, which is more stable. In cesium chloride, the cesium is already in its stable ionic form.
They form cesium sulfide, and the formula is Ce2S.
